I was wondering if there are any formulae for calculating the lift produced by the motion of a hull through the water. Mainly with respect to...
I was wondering if anyone could point me to a decent website which describes how you go about using wooden strips to make a planked model boat. I...
Isnt that kind of like putting a patent on the idea of having flaps on wings? Seems kind of stupid that someone is willing to restrict the...
Wow ive only just sen hydroptere site and i can honsetly say that its the best thing ive seen come out of france in a while(meant in a good way...
Isnt the top battened part of the sail meant to be almost flat anyway i thought this was the point of the square head?
I think we have to make all the parts of the boat ourselves. I think the problem with a peaked up sail is that i will need an actuall gaff section...
What method do you use to get an accurate profile for the fin is it good enough just to judge by eye this is what we did last year. Also heres...
Actually what you say now makes lots of sense. When we were testing it against the weenip class before the race it went faster ina straight line...
I can see what you are saying but that is where it gets more complicated it is not just me that has to sail the boat we have to be able to sail...
I am planning to have a kinda gaff rig but im unsure wether to have a gaff boom or just a stiff batton as i think the head of the sail is meant to...
It looks like some of the other boats in the competition were using panneled sails and i think this is what let us down last year. Am i right in...
In my rc model sails am wondering what the benefits of using paneled sails really are. Surely if they are permanently shaped when they are made...
Well i suppose i could experiment on my rc boat. On an rc boat i think i can make the boom very close to the deck anyway so the deck might act...
I was wondering in my ignorance why they dont have wing tips on sails to stop the air spilling over or does the air not spill over as much in a...
Hey guys hat to bring up this question again but i am getting to the point were i am actually making the sails. The wing sail turned out to be...
IMHO if you are building something that needs to serve a purpose then you need to base your ideas on science to make sure it works. Anything...
Hey guys As some of you may know i have been making a model rc boat at school during my lunch break. We are almost at a stage where the hull is...
Update: Dont know if the race is still going ahead but the wing sail didnt work out it seems far too heavy and would just capsize if we put it...
But surely no more energy can be converted from the water moving relative to the boat/air than can be converted from the air moving relative to...
Thx Doug ill contact the sailetc guy tonight. Could you PM me Lester and Chris' contact info. The drill head is pretty hefty, havnt actually...
